CBET-1335930Zhen HeUniversity of Wisconsin - MilwaukeeSustainable wastewater treatment should significantly clean polluted water while minimizing energy consumption, improving water reuse, and decreasing the carbon footprint. To achieve this goal, exploring new treatment technologies becomes increasingly important. This research aims to scientifically investigate a novel membrane bioelectrochemical reactor (MBER) system for sustainable wastewater treatment that integrates ultrafiltration membranes into microbial fuel cells either in the anode (submerged) or the cathode (side-stream). Such cooperation between the two technologies enables a new treatment system to simultaneously treat wastewater in an energy-efficient way, recover electric energy from organic wastes, and produce high-quality effluent that requires minimal post-treatment. The specific objectives of this GOALI project are: (1) to understand the interaction between fouling-control methods and energy production/consumption in the MBER system; (2) to investigate nitrogen removal in the two MBERs with different membrane installations; and (3) to functionally scale up the MBERs system to a transitional stage. The project will systematically compare hollow-fiber membranes with cross-flow membranes in terms of treatment performance, fouling and economical cost. It will experimentally interpret whether motional granular activated carbon can provide colony sites for electrochemically active bacteria and collect electrons during organic oxidation. It will also examine whether both nitrification and denitrification can be accomplished on the cathode of an MBER system and understand the pathways in which nitrogen is removed. The scaled MBER system will provide a new research platform to bridge fundamental research and system development and fill the knowledge gap on how to scale up a bioelectrochemical system. The project will be carried out through close collaboration with Veolia Water Solutions & Technologies, which will provide substantial support to the project through membrane materials, student training, data analysis, and other active communication/interaction. The project will also involve Pall Corporation, a leading company in membrane materials, as an unofficial collaborator that will provide guidance and help with membrane tests. This project will provide new insights into the development and optimization of a new treatment technology through fundamental understanding of the key problems. It will also reveal the critical relationship between fouling control and energy, which will guide practical operation of the MBER system. The project will benefit the economy (wastewater business) and society (new technology for environmental sustainability) through advancing anaerobic treatment of domestic wastewater and interaction/collaboration with the water industry. The results from the research will help to improve the existing treatment process and to expand the scope of the business with cutting-edge technologies. The research findings will be integrated into current academic programs in environmental engineering to prepare future engineers/scientists for academic and industry careers.

威斯康星州的CBET -1335930zhen heuniversity -Milwaukeesustable废水处理应大大清洁受污染的水，同时最大程度地减少能源消耗，改善水再利用并减少碳足迹。为了实现这一目标，探索新的治疗技术变得越来越重要。这项研究旨在科学研究一种新型的膜生物电化学反应器（MBER）系统，以进行可持续的废水处理，该处理将超滤膜整合到阳极（淹没）或阴极（侧流）中的微生物燃料电池中。两种技术之间的这种合作使一个新的治疗系统可以以节能方式同时处理废水，从有机废物中回收电能，并产生高质量的废水，需要最少的后处理后处理。该目标项目的具体目标是：（1）了解MBER系统中的fouling-Control方法与能源生产/消费之间的相互作用； （2）研究具有不同膜装置的两个Mbers中的氮去除； （3）在功能上将MBERS系统扩展到过渡阶段。该项目将系统地将空心纤维膜与跨流膜进行比较，以治疗性能，结垢和经济成本进行比较。它将在实验上解释运动颗粒活性碳是否可以为电化学活性细菌提供菌落位点并在有机氧化过程中收集电子。它还将检查是否可以在MBER系统的阴极上完成硝化和反硝化，并了解去除氮的途径。缩放的MBER系统将提供一个新的研究平台，以弥合基础研究和系统开发，并填补有关如何扩展生物电化学系统的知识差距。该项目将通过与Veolia Water Solutions＆Technologies进行密切合作进行，该项目将通过膜材料，学生培训，数据分析和其他主动沟通/互动为项目提供大量支持。该项目还将涉及膜材料领域的领先公司Pall Corporation，作为非官方合作者，将提供指导并帮助膜测试。该项目将通过对关键问题的基本了解，为新治疗技术的发展和优化提供新的见解。 它还将揭示结垢控制与能源之间的关键关系，这将指导MBER系统的实际操作。该项目将通过推进对家庭废水的厌氧处理以及与水行业的互动/协作，从而使经济（废水业务）和社会（环境可持续性新技术）受益。研究的结果将有助于改善现有的治疗过程，并通过尖端技术扩大业务范围。研究结果将纳入当前的环境工程学术计划中，以准备未来的工程师/科学家，以促进学术和行业职业。
